Hair curler



HAIR CURLER Filed ont. 12, 1940 M. M. NEWMA N Patented June 16, 1942 UNET 'T 11 Claims.

My invention relates to hair curlers and more particularly to such devices designed to form a curl and .supply a hair pin to the formed curl.

This application is a continuation-impart and an improvement on the device described in my co-pending application Ser. No. 314,193.

As in my former application, the principal object of my invention is to simplify the .procedure of .producing such curls in that the necessary operations are automatically accomplished.

Another object of my invention is to eliminate the conventional clamp found in most curlers While .providing automatic means for initially grasping the hair and nally releasing it.

Another object of my invention .is to provide improved means for enabling the curl to be slid off the end of the mandrel around which it has .been formed.

A further object of my invention is to vprovide a curler of such construction as to .supply a hair pin to a formed curl while automatically collapsing the mandrel and releasing the .grasp of the clamp, all these steps being accomplished in a more positive and efficient manner.

Finally, a most important object of this invention is to further simplify the construction so that the component parts of the device are reduced to a minimum, the construction being in fact much simpler than devices not having the operating advantages above described.

Other objects of my invention will be apparent from the following description, it being understood that the above general statements of the objects of my invention are intended to explain and not to limit it in any manner.

Fig. 12 is a section along 'the line-I 2-12 of Fig. 8.

In the drawing, I5 represents the 4upper mandrel jaw -of the curler, said mandrel jaw being integral with the handle |95. The hollow handle I6 is oblong inV cross-section and is'provided with guide ridges lIl dening a slot It whose inner end is open as shown. On -the handle `I 6 opposite the slot I8 is the closed sloIl IQ. Secured to the inner wall of the handle I6 by the bolt 20 is 'the hair clamping spring jaw 2l.

A member 22 of tubular resilient metal stock has one end thereof disposed `wi-thin the -handle I6 and is vsecured thereto by the pivot pin 23. It will be observed in Fig. 12 Ythat the member 22 is connned against movement in a direction' of the handle I6.

The member '22 'is provided with a cam slot`24 -varranged to be substantially in alignment with the slot I9 of the handle I6. As shown in Fig. 9,

the member 22 has aA spreader 25 integral *therewith and located substantially'inv the path of the slot I8 of the handle I6. The spreader25 is undercut topermit it to be engaged by the Shanks of a hair Aor bobby pin B. The free Iend of the Vmember 22 is bifurcated and the leg 26 has its concavity illled by the member 21 soldered thereto.

The other leg 28 of the bifurcated free end of the member 22 is provided with an opening 29 `and through this opening the hair clamping spring jaw .2l extends so as to be disposed between the legs 28 and 23 of the member 22.

A hair pin actuating slide 33 is provided with a projection 3| which travels in the slot I8 b-etween the guides Il. A pin 32 is connected to the inner wall of said slide 3l! and travels in the slot I9 of the handle I6 and in the cam slot 24 of the member 22. A cap 35 serves. merely to enclose the end of the device and is rictionally or otherwise secured thereto.

My invention operates in the following manner.

The slide 30 being located in the non-operating position illustrated in Fig. 7, a hair pin B is inserted in the slot I8 to embrace the spreader 25 as seen in Fig. 8. Inasmuch as the member 22 is cylindrical, it is capable of rocking movement parallel to the major or transverse axis of the oblong handle I6 and it being desirable at this time to maintain the member 22 outwardly disposed in relation to the mandrel jaw I5, a spring member 33 connected to the member 22 bears against the inner wall of the handle I6 and urges the bifurcated end of the member 22 outwardly. In order to insure the outward disposition of the member 22, a projection 34 is formed thereon (Fig. 10) and bearing as it does against the hair pin B, the member 22 is prevented from inward movement during the formation of the curl. It will be further observed in Fig. that the main body of the cam slot 24 is in alignment with the slot I9 while the curved end of the slot 24 is outwardly disposed.

With the hair pin B and the slide 30 in this position, the operator applies the device to a lock of hair to be curled and the hair, guided by the clamp 2I and the leg 26 of the member 22, is received within the fork of the member 22 and clamped against the leg 26 of the member 22 by the clamp 2l. The clamping action is effected by the outwardly disposed leg 26 bearing against the relatively stationary resilient clamp 2I.

The device is then rotated and the lock of hair is curled around the leg 28 of the member 22, and the upper mandrel jaw` I5.

At this point the slide 30 is actuated and the projection 3| urges the hair pin B along the slot I8, the spreader 25 spreading the Shanks of the hair pin to permit of its subsequent return to normal position, clamping the formed curl. As the slide 3B thus travels, the pin 32 by virtue of the cam slot 24 shifts the member 22 laterally inward, against the action of the spring 33, the direction of movement being perpendicular to the longitudinal axis of the handle I6. This inward movement of the member 22 accomplishes the following results:

l. The leg 26 is urged away from the clamping jaw 2I thusreleasing the formed curl.

2. The mandrel (comprising the member 22 and the upper jaw I5) is collapsed so that the device is easily withdrawn from within the formed curl.

3. The spreader 25, being integral with the member 22, is inwardly displaced allowing the hair pin B to leave the slot I1.

These results are illustrated in Figs. 3 and 4, Fig. 4 showing the leg 26 and clamp 2I in operative relation while the .leg 28 and upper mandrel jaw I5 are separated. Fig. 3 conversely illustrates the separation of the clamping members, i. e. leg 26 and clamp 2l, and the collapse of the mandrel members, i. e., member 22 and jaw I5.

It will be noted that this device avoids the necessity of an independent clamp for initially grasping the hair and this grasping is automatically accomplished when the device is applied to the hair. It will be further noted that the steps of collapsing the mandrel, releasing the clamp, spreading the hair pin, displacing the spreader and clamping the curl are accomplished by a single movement and that the device itself is constructed of only four essential parts, namely,

the handle and integral mandrel jaw, the member 22, the clamp 2I and the slide 30. Thus manufacture and assembly costs are reduced to a minimum while the operation of the device itself is facilitated. In the claims, and for the sake of clarity, the longitudinal mandrel elements jaw I5 and member 22 together comprise what shall be called a mandre I have shown a preferred embodiment of my invention but it is obvious that numerous changes and omissions may be made without departing from its spirit.

I claim:
